    • A stepping clutch device has two annular outer members with inner ratchet teeth, and an inner member having first and second sets of resilient arms having pawl portions engaging said ratchet teeth and recesses of said two outer members, respectively. The arms can be bent by the ratchet teeth in radial direction during relative turning of the outer and inner members in one direction, but couple the inner and outer members slippage-free during relative turning in the opposite direction. The first outer member is fixed, and the second outer member is biassed by a spring toward a first end position in one direction of rotation. Electromagnetic means stepwise turn the second outer member in the opposite direction to a second end position so that the inner member is turned in successive steps in one direction by the spring which is wound up by the electromagnetic means after each step.
    • 步进离合器装置具有两个具有内棘齿的环形外部构件,内部构件具有分别与所述棘轮齿和所述两个外部构件的凹部啮合的棘爪部分的第一组和第二组弹性臂。 外部和内部构件沿一个方向相对转动时,臂可以通过棘轮在径向方向上弯曲,但是在相对转动期间在相反方向上将内部构件和外部构件联接成无滑动。 第一外部构件被固定,并且第二外部构件通过弹簧朝向一个旋转方向的第一端部位置偏压。 电磁装置将第二外部构件沿相反方向逐步转动到第二端部位置,使得内部构件通过在每个步骤之后被电磁装置卷绕的弹簧在一个方向上连续地转动。
